本文对栗疫病菌的菌落形态、α－酯酶、β－酯酶及营养体亲和性（ＶＣ）特征进行了遗传分析。对有性后代的３８个单子囊孢子菌株的研究结果显示：亲本菌株３６６与６８的菌落形态、β－酯酶中（采用聚丙烯酰胺凝胶电泳法）相对迁移率为２．１７和２．３３的２条酶带的遗传分别由１个位点上的２个等位基因控制；α－酯酶中相对迁移为２．５４与２．７７２条酶带的遗传由相互连锁的２个基因位点控制；α－酯酶与β－酯酶间存在完全连锁关系；菌株３６６与６８之间至少存在４个ＶＣ基因差异。
In this paper, the characteristics of colony morphology, α-esterase, β-esterase and vegetative compatibility (VC) in Cryphonectria strains were analyzed. The results of 38 ascospore strains of sexual offspring showed that the colony morphology of the parent strains 366 and 68 and the relative mobility of β-esterase (using polyacrylamide gel electrophoresis) were 2.17 and 2, respectively. 33 were controlled by two alleles at one locus respectively. The relative migration of α-esterase was 2.54 and 2.772 bands were inherited by two genes linked to each other Site control; α-esterase and β-esterase there is a complete linkage relationship between strains 366 and 68 There are at least four VC gene differences.
